PADLOCK.

SiPEGIFIGATIQN forming part of Letters Patent No. 348,864, dated September '7, 1886 Application filed April 20, 1886.

To all whom it may concern Be it known that 1, WILLIAM J. RICHARDS, of Coaldale, in the county of Schuylkill and State of Pennsylvania, have invented a new and Improved Padlock, of which the following is a full, clear, and exact description.

My invention relates to the construction of that form of padlock wherein the shackle or bow is entirely disconnected from the lock when the lock is open; and the invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar figures of reference indicate corresponding parts in all the figures.

Figure 1 is a central sectional view of my improved form of lock. Fig. 2 is a sectional plan view taken on line 00a: of Fig. 1. Fig.3 is a view of the bow or shackle, and Fig. 4 is a side view of the key.

Although I have illustrated my improved form of lock as being inclosed within an oval case, it will of course be understood that the styleor form of the case is entirelyimmaterial, and that a square, round, or other form of case could be employed.

As illustrated in the drawings, the main portion of the case is provided with abottom, 11, in which there is an opening, 12, through which the key is inserted. Upon opposite sides of the case 10 there are formed grooves or ways 12 12, within which the shanks 13 of the shackle 14 ride. \Vithin the case 10, 1 arrange two series of bolts, 2, carried by plates 15, that are provided with flanges 16 and 17, the flanges 17 being arranged to fit close against one of the ridges 18, which, in con- 0 junction with the ridges 19, form the grooves or ways 12, within which the shanks of, the shackle ride. The flanges 16 abut against opposite sides of the case 10, the parts being arranged so that the inner edges of the plates will overlap and closely approach, but not touch, each other, as is best shown in Fig. 2.

After the plates 15 have been inserted in the case 10, as described, a cover, 20, formed with apertures, through which the shanks of the shackle pass, is placed upon the top of the case 10, in which position it is held by rivets Serial No. 199,520. (No model.)

21, said rivets being placed as indicated in Fig. 2, and serving as stops to define the po' sitions of the plates 15.

The bolts 2 are, as before stated, arranged in series, one series being carried by each of the plates 15. These bolts 2 are formed with elongated slots 3, through which there are passed retaining bolts or pins 4, the bolts resting upon horizontal plates 5, extending between the flanges 17 and 16, any upward movement of the bolts being prevented by guiding-pins G. The inner ends of each of the bolts are made in the form of hooks 7, as best shownin Fig. 2, and the bolts are normally held forward within the ways 12 by springs 8, that are mounted in short posts 9, that are carried by the partitions 5, pins 1 being arranged, as usual, in connection with the springs 8. i

In Fig. 4 I fully illustrate the construction of the key which it is designed to employ in connection with the lock described, and this key is provided with as many bits as there are bolts in the lock, and, as shown, these bits are arranged upon opposite sides of the key. The key-shank is hollow, as indicated in Fig. 4, in order that it may ride over or receive the key-spindle 31. Just opposite the hooks 7 of the bolts 2 the plates 15 are formed with appropriately-shaped openings 3 which openings admit the bits of the key.

In operation the key is inserted through the aperture 12', formed in the bottom 11, so that the keyspindle will enter the bore in the keyshank. The key is then turned so that its bits 30 will pass through the apertures 34 in the plates 15 and engage with the hooks 7 of the bolts 2, and a continued motion of the key will throw the bolts out of engagement with the apertures 35 into the bow 14 and into the lock-case against the tension of the springs 8, after which the shackle may be withdrawn from the lock.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, withthe lock-case and hasp, of two plates, 15, overlapping at their inner ends, slotted at 34 in said overlapped portions, and provided with the end flanges, 16 17,bearing against the case, of bolts mounted on the innersides of the plates 15 and having their rear ends adjacent to the apertures 31, substantially as set forth.

2. In a lock, the combination, with a case and its shackle or bow, the said bow being formed with apertures 85, of bolts carried by plates 15, and formed with hooks 7, springs S, key-spindle 31, and a key formed with oppositely-arranged bits,substantiall y as described.

3. A padlock consisting of the case 10, having opposite vertical end ridges, 18 19, forming ways 12, the plates 15, slotted at their inner overlapped ends, as shown at 34', and
